Abstract
An exposure device for homogeneously exposing to light and thus discharging regions of a photoconductive imaging element located outside the regions thereof on which images are to be formed makes use of a lamp housing having a window for passing light to the element and masking member having a terminal edge extending obliquely relative to an axis of the window, and displaceable laterally relative thereto, for covering any desired portion of the area of the window. The masking member can be a tubular member surrounding and turnable about the housing and having a helical edge that can be disposed at any desired location over the window by turning the tubular member. The exposure device can be mounted over a moving photoconductive element such as a photoconductive belt or drum in oblique relation to the direction of movement of the element so that the terminal edge of the masking member will always be parallel to that direction.
